Karnataka, Tamil Nadu, Maharashtra, Bihar, West Bengal, Uttar Pradesh, Gujarat, Haryana, Punjab, Jammu and Kashmir, Madhya Pradesh and Andhra Pradesh are major rose-growing states.

Now a day’s rose farming in greenhouse is more common and commercial as it produces the high quality of flower as compared to open field cultivation.
 

Soils rich in organic matter and well drained sandy loam soils are suitable for Rose cultivation. For good growth, it required pH of 6 to 7.5. Ii is sensitive to water logging so provide proper drainage and remove excesses water.

Avoid saline sodic soils for cultivation. Soil having muram below 45-60m below soil layer are good for plant growth.
 

Rose Classification

It consists of three main groups 1) species 2) old garden and 3) Modern rose.

Species roses:  It also called as wild rose. These types of flowers consist of five petals with bright colors. They last for long time in winter.

To bring soil to fine tilth, carry out ploughing and hoeing operations. Dug and expose soil to sun. It will minimize pest, weed and other infestation.

Then prepared bed for cultivation, 4-6 weeks before planting. While preparing bed for cultivation, add 2ton of well decomposed cow dung and 2kg of Super Phosphate in soil. Then carry out leveling operation for uniform bed formation. Growing rose on bed is more profitable than growing individually in pit.
 

Time of sowing
For Northen states, Mid - October is best time for Rose cultivation. After planting, provide shade, also sprinkled water on plant if strong sunshine is observed. Planting rose in late afternoon gives best results.

Spacing
For surface irrigation, use spacing of 75 X 75cm or 60 X 60cm and for drip irrigation use spacing of 30 X 30cm, 45 X30cm or 45 X 45cm and for flower development use spacing of 50 X 50cm and for oil varieties use spacing of 75 X 75 cm or 100 X 100cm.

Sowing Depth
Plant rose in pit of 30cm diameter and 30cm depth.

Method of sowing
Transplanting of seedlings in main field. Planting should be done.
 

Seed Rate
In green house, rose are planted in 2 rows and density should be 7-14 plants/sq.m.

Propagation of rose is done by budding, grafting, layering, cutting and seed propagation. Budding and cutting more popular method of propagation in rose. 

In Northen Plains, December - February is ideal time for budding (T budding).

Modem roses, miniature, shrub, climber and ramblers are propagated by stem cutting.

Hybrid teas, Floribunda are propagated through budding.

Selection of proper root stock is necessary for grafting and budding method.

Rosa barboniana (Edward rose), Rosa canina(Dog rose), Rosa Indica, Rosa laxa, Rosa manetti, Rosa multiflora are commonly used rootstock.  

Pruning is carried out in second year after planting and then in subsequent years. In Northern plains, rose bushes are pruned in second or third week of October.

Remove dead, dry, diseased and damaged shoots and leaves. Also removes shoots which make bush crowded. Climbing roses don’t required pruning. After pruning, add 7-8kg of well rotten cow dung per bush and mix well is soil.
 

Nutrient Requirement (ppm/plant)

Plant get established and get well settle in field. Irrigation frequency vary according to soil type and climate. Modern irrigation technique like drip irrigation is useful for rose cultivation. Avoid sprinkler irrigation as chances of infection of leaf disease increases.
 

To control the weeds, use Diuron@800gm/acre or Oxyflourofen@200gm/acre or metribuzin@400gm/acre.

• Pest and their control:
  

Caterpillar: If infestation of caterpillar is for effective control take spray of Methomyl along with sticker@1ml/Ltr.

Thrips, aphids and Leaf hopper: If infestation is observed, take spray of Methyl Demeton 25EC@2ml/Ltr of water or Carbofuran 3G@5gm/plant.

• Disease and their control:
  

Leaf Spot: If infestation of black spot is observed, to control take spray of Copper Oxychloride or Mancozeb@2.5gm/Ltr of water. Repeat the spray with interval of 8 days.

Powdery Mildew: If Infestation of powdery mildew is observed, to control take spray of Flusilazole@40ml+Teepol@50ml/100Ltr of water per acre with power sprayer.

Dieback: It is common disease and if not control properly it makes big loss. If infestation is observed, to control take spray of  Chlorothalonil @ 2gm+Teepol @ 0.5ml/Ltr of water with power sprayer.

Economical yield from rose is obtained from second year onwards. Harvesting is done with sharp hand pruners, when color of flower is fully developed and first one or two petals start to unfold but not fully open. Flowers along with prescribed length are cut with hand pruner. According to foreign market standard, for large flower, length of stem varies from 60-90cm and for small flower 40-50cm. Harvesting is to be done early in morning or late in afternoon.

After harvesting keep, roses in plastic buckets/container, filled with fresh water having disinfectant and preservative. Then keep flowers in pre-cooling chamber having temperature of 10oC for 12hours. After then flowers are graded on the basis of stem length, quality etc.
